摘要: Deep cement mixing (DCM) columns are commonly employed as the most effective ground improvement approach in support of road and railway embankments constructed over soft soils with low bearing capacity, insufficient shear strength high compressibility. Finite element modeling is widely adopted to examine performance road, highway during construction, post-construction well serviceability periods. Nevertheless, very limited studies have been conducted on fibre reinforced load transfer platform (FRLTP) DCM supported clays. This paper presents a numerical investigation based fine method (FEM) investigate influence inclusion embankment stress mechanism, overall differential settlements, surface settlement versus horizontal distance from centreline embankment, depth, variations excess pore water pressure, which analysed discussed detail. The findings this analysis indicate that FRLTP can effectively alleviate total settlement, pressure intensity foundation soil, while considerably enhance rigidity, stability mechanism soil-cement columns.
